What's new?
The Deep-Sky Corner was created between 1996 and 2001 as a leisure project by a group of amateur astronomers. Virtual time travel: 1999, 2001, 2002. After that, the Deep-Sky Corner stayed asleep on astro!nfo until September 2020, when that website was discontinued. Now it has risen again on its own domain and is continuously updated.
